Single cone bit is a kind of deceleration little bit, which is the speed of cone is smaller sized than the velocity of drill, mainly disorderly slicing damaged rock. It is suitable for old properly sidetracking and deepening the slim gap drilling operation underneath large rotary speed and drilling strain. 

one. Its application area is broad, not only suited for facet drilling, and can be utilised in deep well. 

two. Operate torque is lower than PDC bit in the exact same drilling pressure and formation issue. It can lessen the tiny dimension hole enlargement buckling difficulties, so that steer clear of down gap accidents. 

three. One cone little bit has benefits of each a few cone bit and PDC bit, and make up the disadvantages of equally. It is far more suited for big plastic development than a few cone little bit, also can be utilized to challenging interlayer which PDC little bit can not deal with other complicated development. 

4. It can realize large speed and particular drilling with down gap motor.
